Oct. 6, 1931. v J. SALlSBURY BUTTONLOOP Filed June 6, 1930 Patented Oct. 6, 1931 A time STATE 5 PATENT? OFFER GOMBANY, OF WEST HAVEN, CONNECTICUT, A- CORBORATION' OF CONNEQTJCUCE' BUTTON LOOP Application filed June 6, 1930:

This invention relates toibutton loops of the type having depending resilient arms having an attached member permitting a rel.- ative movable" association with the depend ing arms.

Theobjjects' ot'the' invention are to provide a two-part eX-pansible button loop of which one part isadapted to be relatively moved out of the plane of the other-part; to provide a two-part eXpansible but-ton loop of which acontracted portion of one part is inexpansibly" held by an axial pulling strain exerted upon the other part; to provide a two -part button loopo-f which one part is rigid and the other part is laterally expansible only upon the axially yielding bodily movement of the rigid part; and to providea two-part button loop with integral connections adapting the manually forced bodily movement of one part to consequentialilyproducea movement of the other part in the plane of the button loop, but-at right anglesto the forced bodily movement. With these and other objects in view the invention consists in the novel constructi'ons, to be herein-after described or claimed, for carrying out the above stated objects and such other objects as hereinafter may beimade to appear.

The character of the invention may be best understood by reference to one illustrative device embodying the novel features herein disclosed and illustrated by the accompanying drawings in which the Figure I is an elevation of the contracted button loop; the Figure 2 is a side elevation of the button loop with apart swung out of the plane of the other part; and the Figure 8 is an elevation of the expanded button loop, the Figure 4 illustrating a modified form by which both parts may be held in a common plane.

The device, as illustrated, comprises an improvement of the button loop disclosed by me in a separate application for Letters Patent of the United States executed this day and filed by me herewith, the improved device including the suspension loop 1, the button-receiving loop 2, the normally contracted throat portion 8, and the button-retaining loop 4, the loops 1, 2, and 4 being axially associated, each one with the others, in that Serial No. 459,472.

a. verticalline- (not illustrated) of; one loop. is thecenter linetof eachof the other loops; Theimproved device is made in two parts, one of which is of resilientwire of which. a. middle "portion is bent to form the suspension loop-1., the v other wire portions depend; ing therefrom-toprovide the spring side arms. 5 and 6 cooperating toprovide the button receiving loop Qand the normally contracted throat portion 3, the wire extremities of theresilient part ofthe loopbeingprovided with the loops 7 and 8.formedsubstantially in the plane of said partas illustrated by the! Fig-i ure 1. The other part out the device is made of wire rigidly formed to provide thebar 9 having the seat 10 for theshanlr Set abut-i ton, and the relativelycouvergent elongated looped ends 11 and 1-2formed. substantially in the plane 0t said rigid partitheiouter portions 13 and 14 of which are engaged by the. loops?v and 8 025 the resilientbutton loop part for a relative slidingmouement between the, button loop-parts Thus, assembled the device is reversible in the sense that an elevation reversed toxthat. illustrated by the Figurehl would be substantially identical there wit When the shank S of a, button, rests within theiseat 10 and is pulled axially of the, button loop in a downward direction axial stress is placed against the bar 9,, as illustrated by the Figure 1, and the rigidly formed part of the device is thereby bodily moved downwardly relative to the resilient part, of the device, and the loops .7 and 8 are thus. made to engage the upper portion of the relatively convergent looped ends 11 and 12, respectively, at which. upper portion the distance between the relatively fixed loops of the rigid button loop part is the minimum, the engager men-t contracting the looped extremities 7 and 8 of the resilient button loop part, and hence the throat portion 3, the contracted condition of the button loop being maintained regardless or" the spring tension of the, arms 5 and 6 so long as the pulling stress is exerted upon the bar 9. Therefore should the tension of the arms 5 and 6 become insuficient to maintain a normally closed throat portion 3, that condition will bemainta-ined by the relatively high position of the loops 7 and 8 in engagement with the convergent looped ends 11 and 12. Upon the passing of the shank S through the throat portion 3, the throat portion is thereby forcibly expanded laterally as illus trated by the Figure 3. In order however that the throat portion 3 be permitted to so expand, the rigid member, comprising the bar 9 and the relatively fixed elongated converging loops 11 and 12, must bodily yield axially of the button loop toward the throat ortion 8; for, as the looped extremities 7 an d 8 of the resilient button loop part expand, the engagement of the extremities 7 and 8 with the upper portions of the fixedly spaced convergent loops 11 and 12 is released to permit the relative sliding movement of the resilient and rigid parts along the plane of the button loop that the expanded looped extremities 7 and 8 may assume positions of engagement with the lower portions of the fixedly spaced convergent loops 11 and 12, as illustrated by the Figure 3.

The Figure 4; illustrates a slight modification of the preferred structure of the button loop, the resilient part of the button loop having the loops 1, 2. and i. the contracted throat portion 3. and the spring side arms 5 and 6, terminating in the looped extremities 7 and 8. respectively, while the rigid part of the button loop comprises the bar 9 having the seat 10 and supporting the fixedly spaced convergent loops'll and 12 comprising in part the outer bars 13 an d 14 respectively engaged by the extremity loops 7 and 8. The modification resides in providing the extremity loops 7 and 8 with the wire extensions 15 and 16. respectively, the extension 15 being made to closely engage against the structure of the loop 11 upon one side of the button loop plane, and the extension 16 made to closely engage against the structure of the loop 12 upon the opposite side of the button loop plane, the extremities 15 and 16 cooperating to maintain the button loop parts within a common plane.
